Replan, Rethink, Repeat: Why Vision-Language Models Make Better Closed‑Loop Planners
Opening — Why this matters now Robotics is rediscovering an old truth: it’s not the plan that matters, it’s the replanning. As more companies experiment with Vision-Language Model (VLM)-driven robotic agents—from warehouse pickers to home-assistance prototypes—a quiet tension is emerging.
